Just wanted to bring it to your attention that I believe Fox's Prayer is incorrectly titled in the donation portion of the Expertise menu. It shows Overlord Armaments prior to entering the donation menu, but once you do the title changes to Murakami while still showing the Overlord icon. I've started checking other items and so far haven't come across any other items that do this, a Murakami named item is above Fox's Prayer in the list though.
